Recent energy codes set the trend for significant improvements to the thermal performance of the building enclosure.  These new codes challenge building owners who desire large expanses of vision glass to utilize higher performance technologies.  The implication of glazing ratio on glazing system U-values and spandrel panel design will be presented including a comparison of prescriptive versus performance-based approach to code compliance.
